NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 339,758. dated Apri1'13, 1886.

Serial No. 184,838. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES W. GANOE, a citizen of the United States, residing at Philipston, in the county of Clarion and State of Pennsylvania, have invented a new and useful Improvement in NutLocks, of which the following is a specification, reference being had to the accompanying drawings.

My invention has relation to improvements in nut-locks; and it consists of the construction and combination of parts, substantially as hereinafter fully set forth, and specifically pointed out in the claim.

The primary object of my invention is to provide means whereby the nuts can be very easily and readily detached, which shall be capable of ready application to and removal from rails of ordinary construction, and which shall be simple and durable in construction, effective of operation, and cheap.

In the accompanying drawings, Figure l is a side elevation of a nut-lock constructed in accordance with my invention, showing in full lines the locking-bar engaging the securing-nuts, and in dotted lines said bar thrown upward out of engagement with the nuts. Fig. 2 is a vertical cross-sectional view through one of the nuts, on the line on a; of Fig. 1. Fig. 3 is a detail perspective view of the locking-bar detached from the bearings and rail, and Fig. 4 is a detail detached view of one of the washers having one of the bearings for the locking-bar.

Referring to the drawings, in which like letters of reference indicate corresponding parts in all the figures, A B designate the meeting-rails; O, the fish-plates or splice-bars fitted over the joint between the said meetingrails D E, the bolts passing through the rails A B and the fish-plates; and D E are the securing-nuts fitted on the threaded ends of the bolts, all of which are of the usual common or any preferred construction.

F designates washers fitted on the throughbolts and interposed between the nuts thereof and the fish-plates, the washers on the two outer end bolts having laterally projecting arms f arranged at their upper ends beyond the edges of the nuts and the heads of the rails. The extreme outer ends of the washerarms have eyes f, or other suitable bearings, and in these bearings are journaled trunnions or supporting-arms h of a nut-1ocking bar, H.

The locking-bar H is provided with a number of spaced arms, h h", two of which are adapted to engage one of the nuts on opposite vertical faces thereof, as shown in full lines in Fig. 1. The spaces between each pair of arms h h" of the locking-bar corresponds to-the distance between the two adjacent nuts of the through-bolts, and the distance between the arms of each pair is equal to the width be tween the vertical faces of the nuts.

In the drawings I have shown the lockingbar as made from a single piece of wire, the locking and journal arms h h h being bent as shown, the locking-arms connecting with each other by cross-bars i; but I do not desire to limit myself to this particular construction, as the bar can be formed from a piece of sheet or bar metal, with notches cut therein to form sockets to inclose and lock the nuts. I prefer, however, to form the locking-bar from a stout piece of spring-wire and to construct the same in substantially the form shown in the drawings, as I have found by experiment that good results are secured by a bar of this construction.

By means of the spring wire locking bar the arms thereof yield to engage the nuts when adjusting the same thereon, and engage said nuts closer and firmer, effectually pre venting them from turning and becoming detached when the bar is in engagement there with.

The trunnions or arms h of the locking-bar being journaled in the bearings of the washerarms, the bar can be very readily turned by hand to assume the position shown in dotted lines in Fig. 1 of the drawings, whereby the nuts can be very easily and readily detached for the purpose of tightening the same, replacing washers that have become useless, &c.

It will be seen that the device can be very readily applied to rails of ordinary construction, it only being necessary to fit washers on the bolts having the journal-arms and fit the supporting-arms of the locking-bar therein; that the device can be quickly adjusted to the nuts to engage the same, or detached there from by turning the bar upwardly on its pivots or trunnions, and that the device is very simple and cheap.

Having thus fully described my invention,

free upper end, located above the plane of the nuts, and the lockingfbar having the arms h h and the trunnions h formed from a single 1 piece of wire, substantially as described, for

what I claim as new, and desire to secure by the purpose set forth. I Letters Patent, is

As an improvement in nut-locks, the combination of the rails, the fish -plates, the through-bolts D, having the nuts, the washers F, fitted on the bolts and interposed between the nuts and fish-plates, and provided with the right-angled arm f, having an eye, f, in its In testimony that I claim the foregoing as myown I have hereto affixed iny signature in presence of two witnesses.
